12/13/2024: while pulling onto the highway, the vehicle suddenly not accelerate past about 18 mph and would not shift gears, only rev the engine louder. Once button was pressed to engage shifting gears manually, the gear number was not shown on the dash as usual, only the letter l. We were able to drive slowly to the next exit ramp to get safely off the road. Notification about engine/transmission popped up on dash and on mygmc app. On star emailed report. Vehicle was towed to local gm dealer and assessed. Have been told that transmission needs completely rebuilt, but no description of actual issue. As of today, 2/5/2025, still waiting on parts to complete transmission rebuild.
This vehicle was bought brand new and has received proper maintenance from one dealership since purchasing. I had to replace the thermostat and radiator before owning the vehicle three years. Within two years of owning the vehicle, my battery went out, which I thought seemed a little early. Then shortly after, I noticed that my locks weren’t engaging when I took my car out of park. Then my car wouldn’t even lock. When I tried to do it on the door control, nothing happened, then when I used my key to do it, it caused the alarm to go off and I couldn’t get it to stop. This resolved after a day, and then it rained again, and it started again. This time, my car wouldn’t unlock and I was trapped in my vehicle and had to open the trunk to get out. This is a known issue according to GMC with no fix. I took it to the dealer, and the codes were saying bcm and told it was being replaced but instead was “serviced”. This issue has begun again, and now I’m being told the locks are the issue and not the bcm, and that may not be covered under warranty. Not being able to get out of your vehicle or not being able to lock your car is a safety issue for passengers leaving them vulnerable to theft, someone entering their car while they’re in it and hurting them. I have had so many issues out of this vehicle and I do not believe I should have to pay for a repair that is a safety issue known to the company. I feel unsafe driving this vehicle now and it doesn’t even have 60k on it. So I’ve estimated on the date of the first incident and the new one just happened this week. The information about this issue can be obtained from my dealership and GMC as it is a known issue with no real fix.
There are currently approximately 22,000 miles on this vehicle. On approximately December 22, 2023, the car was operating normally, and has been since purchased with 3 miles on it, the car was being parked into a flat parking spot at a local store, when the car was stopped completely, the engine/start button was pushed, which normally put the car into park and shut the car down, this time, the car shut down but never went into park and started to drift forward approximately 2 feet before the driver was aware that the car was moving. Luckily there was enough room left when the car was parked if not it would have hit another car or someone else. The passenger door was opened upon shut down and the passenger was getting out and that was the only way the passengers knew the car was still moving. The car or incident has not been reported to the dealer as of now but will be in the near future. There were no warning lamps or messages however the brakes were hit immediately upon recognition and the d light was still illuminated. This issue has not been recreated nor has it happened before.
I had a noise in my front driver side and the car felt like it would pull or sputter. I took it to GMC and they said the bearings are miss threaded in the transmission and it is causing problems with the sputtering and control of the car. They said this is a known problem in GMC but they do not have a recall on the car or the parts to repair it. This is a safety risk because if the transmission is slipping then I could loose control of the car and crash. It can also damage other parts to the car. No warning light or check engine light came on in the car.
